Potentially acid forming (PAF) and non-acid forming (NAF) lands are two types of lands found in ex-coal mine lands. These lands are similar to wetlands that have the potential to produce acid. PT. Jorong Barutama Greston is one of the coal mining companies required by the government to carry out reclamation by revegetation activities. Revegetation of ex-coal mine lands has generated plant biomass and carbon content to a specific value. The purposes of this study were to compare the amount of biomass and carbon content in ex-coal mine lands and to determine the best treatment for the ex-coal mine lands. The methods began with creating the measuring plots on the lands with different soil color (gray and brown). The soil color difference was determined by laboratory analysis test. For each different soil, the land revegetation was implemented with different treatments, 4 ameliorant treatments and 2 fertilization treatments so there were 8 units of treatments. Biomass and carbon content in each treatment unit were calculated by taking 4 plants as the laboratory test samples. The carbon content was calculated using the formula calculating the carbon of undergrowth with a diameter of < 5 cm. The results showed that the biomass and carbon content of plants in plot II were 17 times higher than those in plot I. The best treatment in plot I was the use of lime, bokashi and LOF (Liquid Organic Fertilizer) while the best treatment in plot II was the use of bokashi.

The Special Purpose Forest Area (KHDTK) of Lambung Mangkurat University plays a vital role as a natural laboratory for research, education, and conservation. Monitoring vegetation cover is essential to evaluate the effectiveness of sustainable forest management. This study analyzes the temporal and spatial dynamics of vegetation cover in KHDTK ULM during 2019–2024 using the Enhanced Vegetation Index (EVI) derived from Google Earth Engine (GEE) and assesses the net change over the period. Sentinel-2 imagery was processed into annual composites in GEE and analyzed through EVI classification combined with spatial analysis in ArcGIS. The results show that mean EVI increased from 0.438 in 2019 to 0.529 in 2024, representing a 20.77% rise. Dense vegetation expanded by +1163.26 ha (+111.74%), while medium and non-vegetation classes declined significantly. These changes indicate a major transition from medium to dense vegetation, particularly in the forest core, where as reductions were concentrated along edges dominated by grasslands and open areas. The findings demonstrate that conservation, rehabilitation, and management efforts in KHDTK ULM have effectively enhanced forest recovery and provide a scientific basis for adaptive and sustainable forest education management.

The success of revegetation in post-coal mining areas is generally evaluated through manual field surveys, which are time-consuming, costly, and often subjective. This study offers an alternative quantitative approach using the Red-Green-Blue Vegetation Index (RGBVI) calculated from high-resolution drone imagery to monitor canopy cover in coal mine reclamation areas. The research was conducted on a 1-hectare reclamation site located in Tabalong District, South Kalimantan, Indonesia. UAV flights were carried out using a DJI Phantom 4 Pro at an altitude of 100 meters and analyzed with QGIS 3.34. Vegetation cover was classified using the RGBVI formula with a threshold value of 0.30 and validated through field measurements of canopy diameter. The results showed that canopy cover derived from image analysis reached 69%, while the ground check data indicated 75%, yielding an accuracy level of 92%. The RGBVI effectively distinguished between vegetated and non-vegetated areas and demonstrated a strong correlation with field data. These findings confirm that RGB drone imagery is a reliable, efficient, and low-cost ecological monitoring tool that supports the development of digital reclamation evaluation systems in tropical mining regions.

ABSTRACT Recurrent peatland fires in Banjarbaru threaten ecosystems, public health, and regional economies, demanding integrated, collaborative, and sustainable site-based fire management strategies. The present research goals. The objectives of this study are to identify the factors causing recurrent fires on peatlands, to assess community responsibility in preventing and controlling such incidents, and to examine site-based fire control practices implemented by local residents and related institutions. This research employs a site-based descriptive–analytical approach, in which primary data were collected through field observations (ground check), interviews, and questionnaires administered to 50 respondents using an incidental sampling method. Secondary data were obtained through Focus Group Discussions (FGDs) with the Village Government, the Banjarbaru Disaster Management Agency (BPBD), and local fire-awareness groups, selected using a purposive sampling technique. The results indicate that all recurrent fire events are associated with human activities, particularly land clearing and burning without controlled fire management, discarded cigarette butts, and the spread of fire through dry peat via underground layers. Quantitative data show that 76% of respondents stated that fires spread from other locations. Community practices in fire management remain dominated by reporting behavior (80%), while only 20% participate directly in suppression efforts during idle-land burning. This limited involvement reflects the lack of trained human resources and adequate equipment at the community level. Control measures have been implemented through the construction of firebreaks and water channels as part of peatland hydrological management. However, fires will continue to occur and recur if local residents and related institutions do not actively maintain these facilities. This study concludes that peatland fire control must be implemented in an integrated manner, involving local communities at the site level in collaboration with stakeholders and government institutions. Keywords: preventing, peat fires, community participation ABSTRAK Kebakaran lahan gambut berulang di Banjarbaru mengancam ekosistem, kesehatan masyarakat, ekonomi regional, serta menuntut pengendalian berbasis tapak berkelanjutan kolaboratif terpadu. Tujuan penelitian saat ini adalah untuk mengidentifikasi faktor-faktor yang menyebabkan kebakaran berulang di lahan gambut, untuk menilai tanggung jawab masyarakat mengenai pencegahan dan pengendalian insiden, dan untuk membahas pengendalian kebakaran berbasis praktik penyadapan yang diterapkan oleh penduduk setempat dan lembaga terkait. Penelitian ini merupakan studi deskriptif-analitik berbasis site-tapping dimana pengumpulan data utama dilakukan di lapangan melalui ground check, wawancara, dan kuesioner terhadap 50 responden menggunakan metode incidental sampling. Data sekunder dikumpulkan melalui FGD dengan LURD, BPBD Banjarbaru, dan Amendemenselites yang diatur dengan metode purposive. Hasil penelitian menunjukkan bahwa semua kejadian kebakaran berulang semuanya terkait dengan aktivitas manusia, terutama pembukaan dan pembakaran ulang tanpa api yang terkendali, puntung rokok, dan penyebaran api di gambut kering oleh lapisan bawah tanah. Berdasarkan data kuantitatif, 76% responden mengklaim bahwa kebakaran menyebar dari sumber lain. Praktik masyarakat dalam penanganan kebakaran tetap didominasi oleh pola pelaporan dengan 80%, dan 20% lainnya melalui bantuan selama pembakaran perkebunan yang menganggur, yang berlangsung pada tingkat minimum karena masyarakat tidak memiliki sumber daya dan sarana terlatih untuk membantu selama terjadinya kebakaran. Kegiatan pengendalian dilakukan dengan pembuatan sekat bakar dan saluran-saluran air sebagai bagian dari pengelolaan hidrologi) akan tetapi kebakaran akan terjadi dan terjadi kembali jika penduduk setempat dan lembaga terkait tidak aktif memelihara fasilitas tersebut. Penelitian ini menyimpulkan bahwa pengendalian kebakaran lahan gambut harus selalu dilakukan secara terintegrasi baik oleh masyarakat ditingkat tapak, maupun stakeholgder dan pemerintah.

The challenge for forestry education is both the transfer of technical knowledge and whether students are adequately prepared to practice in the field. We examined the relationships among the four variables: Seedling Understanding (SU), Curriculum Relevance (CR), Learning Motivation (LM) and Practical Readiness (PR) among forestry undergraduates. We employed a quantitative, explanatory design based on data from 54 students taking a Seedling Techniques course. PLS-SEM was used for measuring and structural models testing. Results show that curriculum relevance (β = 0.487) and seedling understanding (β = 0.349) significantly increase learning motivation, which strongly predicts practical readiness (β = 0.627; R² = 0.798). These findings highlight the importance of motivation-driven curriculum design to enhance practice-ready forestry graduates. These results imply that technical understanding and curriculum design are necessary but only lead to readiness because of their motivational impact on students use or integration of those skills; using lessons learned to motivate student engagement and further application of practical knowledge. This integration of cognitive, pedagogical, and motivational dimensions into a single empirical model is a unique aspect of the study and extends the motivational theory currently present in the literature to include forestry education. In practical terms, the results provide some suggestions on the development of curricula and teaching strategies that incorporate relevance, autonomy and practice to develop competence and preparedness.

This study aimed to analyze vegetation recovery dynamics in Kiram Village, Banjar Regency, South Kalimantan, Indonesia during the period 2023–2025 using the Normalized Difference Vegetation Index (NDVI) derived from Sentinel-2 satellite imagery. A multi-temporal NDVI approach combined with NDVI change detection was applied to identify vegetation recovery trajectories and determine restoration priority zones. The results indicate a clear improvement in vegetation condition during the study period. The combined area of non-vegetation and low vegetation classes decreased from 11.47% in 2023 to 4.13% in 2025. In contrast, the medium vegetation class increased from 83.24% to 86.19%, while the high vegetation class increased from 5.29% to 9.69% over the same period. NDVI change detection further revealed that the study area could be classified into three vegetation recovery zones: rapid recovery, stable, and low-recovery zones. The dominance of medium vegetation, covering more than 80% of the study area, indicates that the Kiram landscape is currently in an intermediate vegetation recovery stage. These findings demonstrate that multi-temporal NDVI analysis is an effective approach for monitoring vegetation recovery dynamics and identifying priority areas for ecosystem restoration at the village landscape scale.

ABSTRACT Community based waste management is increasingly recognized as a key component of circular economy transitions in developing countries. Its potential contribution to forest protection remains underexplored. This study aims to assess how the operational performance of a community-based waste bank reflects circular economy dynamics and its potential relevance for forest resource conservation study examines the role of waste banks as indirect instruments for forest resource conservation. The analysis is conducted at Bank Sampah Urban Dewan, a community waste bank in Indonesia,nal data from a community based waste bank system over the period 2021 – 2025. A time series approach is applied to examine trends in recovered waste, material composition, and participation adjusted recovery intensity (kg per customer per year). Results indicate that paper consistently represents the dominant recovered material, followed by plastic and cooking oil used. While total recovered waste increases over time, waste management intensity varies substantially, reflecting dynamic participation patterns. The dominance of paper recovery suggests a material substitution pathway, whereby increased availability of secondary fibers may reduce reliance on virgin forest-based resources. In this study, recovery intensity is employed as an operational proxy for circular economy performance and potential indirect forest pressure reduction. The findings highlight that waste bank can generate cross sector co-benefits beyond urban waste reduction, contributing to sustainable consumption and production (SDG 12), climate action (SDG 13), and life on land (SDG 15). Although causal impacts on deforestation are not quantified, the study provides empirical evidence supporting the integration of community-based waste management into broader forest and sustainability policies. This research advances the waste forestry nexus literature and offers a replicable analytical framework for assessing the indirect environmental benefits of circular economy interventions. Keywords: community-based waste management, forest resource protection, sustainable development goals, waste bank ABSTRAK Pengelolaan sampah berbasis komunitas semakin diakui sebagai komponen penting dalam transisi menuju ekonomi sirkular di negara-negara berkembang. Potensi kontribusinya terhadap perlindungan hutan masih belum banyak dieksplorasi. Penelitian ini bertujuan untuk menilai bagaimana kinerja operasional sebuah bank sampah berbasis komunitas mencerminkan dinamika ekonomi sirkular serta relevansinya bagi konservasi sumber daya hutan, sekaligus mengkaji peran bank sampah sebagai instrumen tidak langsung dalam perlindungan sumber daya hutan. Analisis dilakukan di Bank Sampah Urban Dewan, sebuah bank sampah komunitas di Indonesia, menggunakan data operasional sistem pengelolaan sampah berbasis masyarakat selama periode 2021–2025. Pendekatan deret waktu (time series) diterapkan untuk mengkaji tren volume sampah yang dikelola, komposisi material, serta intensitas pengelolaan yang disesuaikan dengan tingkat partisipasi (kg per nasabah per tahun). Hasil penelitian menunjukkan bahwa kertas secara konsisten merupakan material yang paling dominan dipulihkan, diikuti oleh plastik dan minyak jelantah. Meskipun total sampah yang dikelola meningkat dari waktu ke waktu, intensitas pengelolaan sampah berfluktuasi secara signifikan, mencerminkan dinamika pola partisipasi masyarakat. Dominasi pemulihan kertas mengindikasikan adanya jalur substitusi material, di mana peningkatan ketersediaan serat sekunder berpotensi mengurangi ketergantungan pada sumber daya berbasis hutan yang bersifat primer. Dalam penelitian ini, intensitas pemulihan digunakan sebagai proksi operasional untuk kinerja ekonomi sirkular dan potensi pengurangan tekanan terhadap hutan secara tidak langsung. Temuan ini menegaskan bahwa bank sampah dapat menghasilkan manfaat lintas sektor yang melampaui pengurangan sampah perkotaan semata, dengan berkontribusi pada tujuan konsumsi dan produksi berkelanjutan (SDG 12), aksi iklim (SDG 13), serta perlindungan ekosistem daratan (SDG 15). Meskipun dampak kausal terhadap deforestasi belum dapat dikuantifikasi secara langsung, penelitian ini memberikan bukti empiris yang mendukung integrasi pengelolaan sampah berbasis komunitas ke dalam kebijakan kehutanan dan keberlanjutan yang lebih luas. Penelitian ini memperkaya literatur mengenai keterkaitan antara pengelolaan sampah dan kehutanan serta menawarkan kerangka analitis yang dapat direplikasi untuk menilai manfaat lingkungan tidak langsung dari intervensi ekonomi sirkular.

ABSTRACT Mangrove forests in the Barito River estuary exhibit dynamic changes that occur alongside land accretion processes and variations in hydrological conditions. This study aims to analyze the relationship between mangrove canopy density and water dynamics using the Combined Mangrove Recognition Index (CMRI) and the Modified Normalized Difference Water Index (MNDWI) on Pulau Kaget and Pulau Tempurung during the period 2005–2025. The analysis was conducted using multi-temporal Landsat imagery at five-year intervals, including CMRI and MNDWI mapping, change detection analysis, time-series evaluation, and Pearson correlation testing. The results indicate an increase in mean CMRI values on both islands, with the most pronounced increase observed on Pulau Tempurung, where CMRI values more than doubled compared to initial conditions. In contrast, mean CMRI values on Pulau Kaget tended to stabilize after 2010 due to limited space for further accretion. MNDWI analysis shows a reduction in water area on both islands, with land proportion increasing from 82.98% to 88.82% on Pulau Tempurung and from 89.77% to 93.55% on Pulau Kaget. Correlation analysis reveals a negative relationship between CMRI and MNDWI (r = −0.596), indicating that increasing mangrove density is associated with land accretion processes. These findings confirm that the integration of CMRI and MNDWI is effective for monitoring the spatial–temporal ecological and geomorphological dynamics of mangrove ecosystems. Keywords: barito estuary, mangrove forest, spatial ecology, vegetation succession ABSTRAK Hutan mangrove di muara Sungai Barito memiliki dinamika yang berlangsung seiring dengan proses akresi lahan dan perubahan kondisi perairan. Penelitian ini bertujuan menganalisis hubungan kerapatan mangrove dan dinamika perairan menggunakan pendekatan indeks CMRI (Combined Mangrove Recognition Index) dan MNDWI (Modified Normalized Difference Water Index) pada Pulau Kaget dan Pulau Tempurung selama periode 2005–2025. Analisis dilakukan menggunakan Citra Landsat 5 TM serta Landsat 8/9 OLI/TIRS dengan interval lima tahunan, meliputi pemetaan CMRI, MNDWI, deteksi perubahan, analisis deret waktu, serta uji korelasi Pearson. Hasil menunjukkan peningkatan rerata CMRI pada kedua pulau, dengan peningkatan paling menonjol terjadi di Pulau Tempurung yang meningkat lebih dari dua kali lipat dibandingkan kondisi awal periode pengamatan. Data pada Pulau Kaget, rerata CMRI cenderung stabil setelah tahun 2010 seiring terbatasnya ruang akresi. Analisis MNDWI menunjukkan penurunan luasan perairan pada kedua pulau, di mana persentase lahan meningkat dari 82,98% menjadi 88,82% di Pulau Tempurung dan dari 89,77% menjadi 93,55% di Pulau Kaget. Uji korelasi menunjukkan hubungan negatif antara CMRI dan MNDWI (r = −0,596), yang mengindikasikan keterkaitan antara peningkatan kerapatan mangrove dan proses akresi lahan. Temuan ini menegaskan bahwa integrasi CMRI dan MNDWI efektif untuk memantau dinamika ekologis dan geomorfik mangrove secara spasial-temporal.
